## How These Metrics Relate

Video metrics form a retention funnel:

```
Video Plays → Video Views (6s) → 25% → 50% → 75% → 100% Completion
```

* **Video Plays** > **Video Views** because plays include very short watches
* Each completion tier is a subset of the previous
* Drop-off between tiers reveals where viewers lose interest

## Choosing the Right Metric

* **Awareness campaigns**: Use Video Views (6s) as the standard metric
* **Engagement optimization**: Compare 25%/50%/75%/100% completion rates
* **Creative testing**: High plays but low completions suggest hook issues
* **Cost analysis**: Use Cost per View metrics to compare efficiency
